--- Comment #12 from Christophe Lyon <clyon at gcc dot gnu.org> ---
Following Jakub's recommendation, I applied this:
diff --git a/gcc/tree-stdarg.c b/gcc/tree-stdarg.c
index 18dd972..edf47d1 100644
--- a/gcc/tree-stdarg.c
+++ b/gcc/tree-stdarg.c

- gimple_seq_add_seq_without_update (&pre, tmp_seq);

}
input_location = saved_location;
on top of r246319 (that is, before you reverted it).
and my build now completes. I didn't run make-check though.
